Thank you so much for your explanation. It makes sense.

I have a similar question. Why are we not taking the common factor 2(L*B*H)?

This may is more of a conceptual question I guess. In 2l *2b*2h can we not take the 2 common such as 2(L*B*H).
L*B*H=10.....-> given.
2L*2B*2H= ?
2(L*B*H)
2(10)=20
Hi
dixxa,
Common factors are to be factored out when the terms are either added or substracted in an equation/expression. In case of multiplication or division, it is simply multiplication or division of terms respectively.
Here, in 2L*2B*2H, we have three terms multplied 2L, 2B, and 2H.
From 2L, 2 can be factored out. (you know 2L=2 multiplied by L)
Similarly, From 2B, 2 can be factored out.
Similarly, From 2H, 2 can be factored out.
Now, 2L*2B*2H=2*2*2*L*B*H=8(L*B*H)
Had it been 2L+2B+2H, then we can factor out 2 as '2' is a common factor of 2L, 2B, and 2H, making 2L+2B+2H=2(L+B+H)
Hope it clarifies your query.
